Struct FontVariation 

pub struct FontVariation {
    pub tag: Tag,
    pub value: f32,
}

OpenType font variation setting (tag + f32 value).

Fields

tag: Tag

The OpenType tag for this setting.

value: f32

The variation value.

Implementations

impl FontVariation

pub const fn new(tag: Tag, value: f32) -> FontVariation

Creates a new variation setting.

pub fn parse_css_list( s: &str, ) -> impl Iterator<Item = Result<FontVariation, ParseSettingsError>> + Clone

Parses a comma-separated list of variation settings according to the CSS grammar.

On success, yields a sequence of settings. On failure, yields a ParseSettingsError.

Supported syntax is a comma-separated list of entries:

• tags are required and must be quoted: "wght" 700 or 'wght' 700
• values are required and are parsed as f32

Grammar (simplified): list := ws? entry (ws? ',' ws? entry)* (ws? ',')?

Whitespace is ignored and a trailing comma is permitted, but empty entries (such as ,,) are rejected.

Trait Implementations

impl Clone for FontVariation

fn clone(&self) -> FontVariation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FontVariation

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for FontVariation

fn eq(&self, other: &FontVariation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
